Wet potassium dichromate crystals (90% crystals and 10% entrained solution) are fed to a dryer where they are contacted with dry hot air. The entrained solution is saturated at 30°C and contains 0.2 kg solute per kg of water. The air leaving the dryer has a dew point of j9.2 °c. Determine the flow rate of inlet air in L/h at STP conditions, for a production rate of 1000kg/h of dry dichromate crystals.
